What is curtain close?

Curtain close is a theatrical term referring to the moment when the curtain falls and the stage goes dark at the end of a performance or act. This typically signals the end of a play or musical, or the transition between scenes or acts. The curtain itself may be made of various materials, such as fabric or metal, and is often electronically controlled and operated by a stage crew. The timing and execution of the curtain close can have a significant impact on the overall theatrical experience, as it can help to build tension and anticipation, or provide a satisfying resolution to the story being told.
